FREDERICK H. CHEYNE, OF BRAMPTON, ONTARIO, CANADA.

STREET AND STATION INDICATOR.

SPECIFICATION forming part of Letters Patent No. 388,828, dated September 4, 1888.

Application filed January fl, 1888. Serial No. 260,002.

To all whom it may concern.-

Be it known that], FREnERIeK HERBERT CIIEYNE, of the town of Brampton, in the county of Peel, in the Province of Ontario, Canada, mechanic, have invented certain new and useful Improvements in Station and Street Indicators, of which the following is a speciiieation.

My invention relates to certain improvementsin the mechanism of a station and street indicator described in my United States patent, No. 371,737, and in my Canadian patent, No. 25,797; and the object of the present invcntionv is to simplify the mechanism by which the motion of the wheels is conveyed to and operates the mechanism of the indicator; and it consists, essentially, in the simplification and arrangement of the parts hereinafter more particularly explained.

Figure 1 is a front view with parts removed and other parts broken away. Fig. 2 is a perspective view, partly in section, of the upper winding-roller detached.

In the patents referred to the vertical rod D is driven in the manner in which I intend to impart motion to the Vertical rod marked A in the drawings attached to the present application, and the wheel B in my present drawings is made in the same manner and for the same purpose as the wheel I in the patents I have referred to, the only difference being that the wheel B is driven bya worm, C, fixed to the vertical rod A, as indicated. It will therefore be understood that as long as the car is in motion the rod A will revolve and consequently impart a corresponding and slower rotary movement to the wheel I The paper on which the names of the stations or streets is printed is carried on the rollers I) and E, and is caused to travel in the manner hereinafter described by the motion of the said rollers, which are driven from the vertical rod A in the following manner: A shaft, F, is suitablyjournaled, and is provided with a bevelpinion, G, which meshes with a corresponding pinion, II, fixed to the vertical shaft A, as shown. On the opposite end of this shaft F, I fix a grooved pulley, I, which is connected to the grooved pulley J on the roller E by means of the cord K, and a cord, L, connects the pulley J with the pulley M, fastened to the roller D, as indicated. The cords K and I1 (No model.)

are made sufficiently taut to convey motion to their respective rollers; but they are intended to slip should anything impede the motion of either of the said rollers, and it is in order to regulate the necessary stoppages in the motion of the rollers that the mechanism I shall now describe is designed.

On one end of the roller E, I fasten a spurwheel, N, into which the end of the rod 0 drops when it is desired to arrest the motion of the rollers D and E. In the drawings, the rod 0 is held clear of the spur-wheel N, so that when it is in the position shown the said rollers are in motion; but when the rod 0 is in the position in which it is indicated by dotted lines the rollers D and E are stationary.

In order to describe the operation of the mechanism which raises and drops the rod 0, I show the roll of paper in dotted lines, with the words York St. at the top. The course of the paper is indicated in Fig. 1, from the roller D up over the spindle d, thence down around the spindle 0, back to the spindle f, thence up around the roller E. For the purpose of illustration, I show the roll of paper traveling in the direction indicated by arrow. I punch holes 0, shown in dotted circles in the roll of paper at certain spaces apart, which may be increased according to the size of the advertisement placed in the same space as the name of the street or station. The rod 0 is held up during the period that the roll of paper is traveling by the dog P, which projects into the notch a in the rod 0; but immediately the standard Q reaches one of the holes 0, which it is indicated as approaching in Fig. 1, it drops into a hole, I), in the block It and tilts the pivoted lever S. This movement raises the short end of the lever S, and the dog I? is thrown back against the pin (7, by the end of the lever S striking against the notch c in the dog I. The red O is held down bythe spring Z, it being now released from the dog P,and the roll of paper is thus prevented from revolving. c is a pin fastened to the rod 0, and held above the arm T by the dog I when the rod 0 is in the position indicated in Fig. 1. When the rod 0 drops into the spur-wheel N, as described, the pin 0 is immediately above the arm T, which is held in position by the spring 2. The arm T is formed with a curved slot, 1/, in which rides the pin 1/, secured to the side of the ease, and its other end engages the short arm of the lever S, which is pivoted at s to the supports, there being a loose engagement between the arm T and lever S, as shown in Fig. 1.

In order to raise the end of the rod 0 from the spur-wheel N and at the same time raise the standard Q out of the hole I), and thus allow the roll of paper to continue revolving, I place on the rod A the cam g, which in revolving acts upon the end of the lever h, the other end of which is connected to the arm Tby the cord or wire 2, as follows: Vhen the rod A in revolving brings the wide portion of the cam 9 against the inner end of the lever h, it tilts it on its pivot and raises the end of the slotted arm T by means of the cord i. The arm T in moving presses the pin 0 upward and raises the rod 0 out of the spur-wheel N, thus allowing the roller D to revolve in the direction indicated and carry the paper forward till the end of the standard Q dropsinto the next hole.

U is a bar connected by the spring 1' to the back of the case, and having a plate, a, fastened at one end, sliding in the guidesj, while the other end of the bar U slides upon the center-pin K of the wheel B. On the bar U, I place a sleeve, 1, into which is fitted a pin, m. The pin m drops into one of the holes at in the groove 1) when it is desired to indicate the station or street; but at the moment the rod 0 is raised the eccentric q upon the rod A pushes the sliding bar U from the face of the wheel 3, thus drawing the pin at out of the hole n and leaving the wheel B free to be revolved by the worm 0 till the next hole n is reached.

Having now described severally the operation of the principal parts, Ishall now describe the operation consecutively and conjointly.

\Vhen the pin m is drawn out of the hole n, it travels along the groove 2) in the wheel B, which is caused to revolve, as before described, by the worm C. At the same time the rollers D and E are caused to revolve and bring the roll of paper in the direction indicated by arrow till the hole 0 reaches a point directly beneath the standard Q. The standard Q now drops into the hole I), tilts the lever S, throwing the dog P out of the notch a, and thus allowing the rodOto drop into the spurwhecl N and stop the roll of paper from revolving. The cord K now consequently slides on the pulley J, which still revolves. The worm O continues to bring the wheel B around, and the pin m passes along the groove till it reaches the next hole, n, into which it drops. At this period the wide portion of the cam g strikes the end of the lever h, and, as before described, brings the rod 0 and the dog P back into their initial positions, as indicated in Fig. 1. The eccentric (1 now pushes the spring-bar U from the wheel I thus drawing the pin m from the hole a and the end of the lever it out of the circuit of the cam g. It will now be seen that the worm C will cause the wheel B to revolve until the pin in drops into the next hole, n, without affecting any mechanism for driving or stopping the rollers. As the wheel B is revolving, the pin m continues in the groove 9); but immediately the pin m drops into the hole a the arm U is drawn toward the wheel 13 by the action of the spring 1'. \Vith the view of having my mechanism operate without reference to the way the car is going, I form theupper roller, 1), asshown in Fig. 2. The spindle s of the roller 1) is made hollow and revolves with another spindle, t, to which it is connected by the pin 1/.

V is a ratchetwheel held in frictional contact with the end of the roller I) by the spiral spring 1).

It will be understood on reference to Fig. 1 that when the paper is revolving in the direction indicated in that figure the dog to, engaging with the ratchet V, will prevent the paper from slipping as it is being wound upon the roller D. On referring again to Fig. 2, it will be seen that the pulley M has an internal ratchet. W', cut in it. :r is a dog pivoted on the end of the roller D. The dog m engages with the internal ratchet, \V, and makes it re Volve along with the roller 1) when it is turn ing in the direction indicated in Figs. 1 and 2. \Vhen, however, the roller E becomes the winding-roller and the paper runs in the opposite direction to that indicated in these figures, the pulley M revolves without the roller D, on account of the dog 00 slipping over the teeth of the internal ratchet, \V. The dog to also slips over the ratchet V; but as the face of the ratchet is brought to press against the end of the roller D by the spring 1) it serves to make the roller 1) turn slowly and thus puta tension on the paper and keep it taut as it leaves the roller. The pulley M has pins 3 on it, which strike against the L-shaped end of the crank-spindle Y, which in turning operates the hammer ot the bell, as indicated in Fig. 1, at the period when the name of each station or street on the roll of paper is moving into position.

\Vhat I claim as my invention is- 1. The roller E, having a gear-wheel, N, secured on one end, in combination with the standard Q, which drops in the hole I) when the roll of paper X brings one of the holes, 0, underneath the standard, which in dropping tilts the lever S and throws up the short end of the lever against the notch c of the dog I, which is thus raised out of the notch a, thereby allowing the rod 0 to drop into engagement with the gear-wheel N, substantially as and for the purpose specified.

2. The rod 0, sliding in suitable guides and having a spring, Z, notch a, and pin 0, in combination with the slotted arm T, held in position by spring 2 and connected by the cord t to the lever h, which is acted upon by the cam 5;, so as to cause the arm T to raise the pin 0 and bring the dog P opposite the notch a, into which it falls, substantially as and for the purpose specified.

The bar U, one end of which slides on the pin is, while the other end, u, slides in the guides j, in combination with a lever, h, pivoted on the said end a, the rod 0, pin 0 thereon, slotted arm T, and the cord 1', connecting one end of the lever 71 with the arm T, substantially as and for the purpose specified.

4. The wheel B, having groove P and holes a, and the bar U, provided with a sleeve, Z, into which is fitted a pin, m, past which the groove p of the wheel B revolves until the hole it comes opposite to the pin m, in combination with the spring r, acting on said bar, and designed to bring the pin in into the hole a, substantially as and for the purpose specified.

5. The wheel B, having groove P and holes a, and the bar U, one end of which slides on the pin 7C, while the other end, a, slides on the guides in combination with the lever 11, the cam g acting thereon, and the eccentric (1, designed to push against the bar U, thus drawing the pin at out of the hole a, and at the same time bringing the end of the lever h out ofthe circuit ofthe cam g, substantially as and for the purpose specified.

6. The roller 1), having a hollow spindle, 25 s, which is connected. to the spindle t, with which it revolves, by the pin a, in combina tion with the dog 10, which engages with the ratchetwhcel V, having an internal ratchet, \V, which is engaged by the dog X on the end of the roller 1), substantially as and for the purpose specified.

7. The roller 1), revolving on the spindle I, in combination with the hollow spindle s of said roller, engaging the said spindle t, the ratchet-wheel V, the face of which is held in frictional contact with the end of the roller 1) by the spiral spring 0, and the dog 10, engaging said ratchet around said spindle 8, substantially as and for the purpose specified.
